Be it known that we, EDWARD F. .NAssoir and YGno'ne'n E. JoHNsoN,citizens of the; United States, 'resi'dingat Sparks, in the county ofNVashoe and State of Nevada, have invented new anduseful Improvements inLantern Attachments, of which the fol-f lowing isa specification. 1.

This invention relates to lanterns, particularly to'those used byrailroad men for: signaling and other purposes and has forits object theprovision of an attachment for a. lantern of this character adapted toreplace the oil font and burner whereby to convert the lantern into anelectrical lantern, the attachment being in the nature of a lanterncontaining a plurality of dry cells and have ing a socket carrying anincandescent bulb.

An important object is the provision of an attachment of this'characterwhich isncorr be slipped into the bottom portion of a rail road lanternafter the oil burner and font thereof have been removed, thenattachmentbeing held iniplace by a holder engaging against the top thereof and;against the top of thelanter 1 w Another object is the provision of adevice of :this character which has built thereinto a simple switchmechanism 'whereby the current maybe ttuned on or off, as desired. Anadditional object is the provision. of a device ofthis character whichwill. be simple and inexpensive in manufacture, easy to in stall, highlyefficient in use, durable in service, and a general improvement in theart.

lVith the above and other objects and ad vantages in View, the inventionconsists in. the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings inwhich Figure l is a side elevation of the lantern, Figure 2 is avertical longitudinal sectional view, I

.Referring more' 'particularly to the draw ings, the letter A designatesthe-wire frameof :the lantern which is shown as being off I the wellknown type used 'trainmen and others,-'and Bdesignat'es theitop, hingedas. shown atC, and provided with a catch D for holdingit closed.Depending fromtliis' .top is the usual flangeE. fThe letter F designatesthe handle which is connected with the'frame A in the usual mannerwhereby to be either pivoted or to be locked rigidly The letter-Gdesignates the base or bottom of the "lamp which is secured within thelower fportion'oftheframe A and which 7 ordinarilycontains the oil fontandsupports' the burner. 'lh'e oil font and burner'are not showncarrying out the'presenti vention they must-be removed. I

' ;Ingcarrying o utour invention provide, -,a1:shell.-10 which'is'formed as an inve rted cup memberand which is'provided with "anoutwardly:extending flange 111 adapted to" seat upon the top of the baseG5 Formed inv the-center of the top of thisshell is asoc-k'et 12 withinwhich is screwed the shank of an inc'andescentbulb 1'3. Disposedwithinthis shell is a battery'lt form'ediof anysu-itable' number of dry cellsconnected, or'it may be preferred touse a single large cell. Thisbattery is'enclosed withina protective casing 15 -which' may beofcard-board or the like and-within-theupper-end of which is-diswhich isof course electrically .connected with the cells to form one terminal.Located posedan upwardly spring-pressed plate 16 within one side of thecasing 15 is a metallic strip 17 which forms the other terminal. Thisbattery seats within the'base firmly engaged within the shell 10.

In order to prevent dislocation of-this attachment weprovidea disk 18flanged, as shown at 19, "and adapted to engage the flange E of the topB; Depending from this G and is' disk at diametrically opposite pointsare rods 20 which carry at their lower ends ar-v cuate plates 21 whichengage against the outi side of the shell l0-and which engagethe'top ofthe flange 11 for holding the shell and battery firmly in positionwithin the base G. The socket 12 carried by the shell extends through acentral hole 22 in the top of the casing 15 and engages thespring-pressed plate 16.

The switch structure associated with the device comprises a block 23 ofinsulating material secured upon the inside of the shell 10. v iecuredupon this block is a leaf-spring 24 which when the parts are assembledon gages the metallic strip 17. Secured transversely of this block 23 isa strip 25 and journaled through this strip and through the block andshell is a rod 26 having an angular end 27 serving as a handle. Thespring 24 terminates in spaced relation to the strip Secured upon therod 26 is a contact arm 28 which is of course grounded on the shell andthis contact arm is movable to engage the spring 24 so as to completethe circuit through the bulb.

In the use of the device it will be seen that the battery is disposedwithin the base G with the shell 10 fitting upon the top thereot. Theseparts are held in position by an auxiliary frame including the disk 18,rods 20 and plates 21. lVhen the rod 26 is turned to bring the arm 28into engagement with the spring 24:, the current will flow through andenergize the incandescent bulb 13, as will be obvious. lVhen the use ofthe device is not desired, it is merely necessary to turn the handle 2'?through an arc of ninety degrees, whereupon the current will be cut offand the lamp deenergized.

From the foregoing description and a study of the drawings it will beapparent that we have thus provided a simply constructed andconsequently inexpensive device for transforming an oil lantern into anelectrical lantern, the device being easily installed and being sosimple as not to get out of order, as well as having the great advantageof not being subject to being blown out by wind or rain.

\Vhile we have shown and described the preferred embodiment of ourinvention it is of course to be understood that we reserve the right tomake such changes in the form, construction, and arrangement of parts asengaging against the underside of the top of the lantern, rods dependingfrom said disk,

and plates carried by the lower ends oi said rods and engaging saidshell whereby to hold said shell down.

2. In a lantern including a supporting frame and a base, an attachmentreplacing the oil font and burner ordinarily disposed within the base,the attachment comprising a battery of dry cells enclosed within acasing and fitting within the base, the top of the casing having a hole,a spring-pressed plate within the casing electrically connected with thebattery to form one terminal thereof, a shell fitting upon said batteryand seating upon said base, a socket carried by said shell, projectingthrough said hole and engaging said plate, a bulb within said socket,and a switch mechanism carried by the shell and connected with thebattery and the bulb whereby to complete the circuit' there through,said switch mechanism comprising a metallic plate on the casingconnected with the battery and formingthe other terminal thereof, ablock of insulating material secured within said shell a leaf-springcarried by said block and engaging said'metal-lic strip, a cross stripon said block, arod journaled'through the shell, the block and the crossstrip and having its outer end. formed with a handle, and a-n'arm onsaid rod mov able to engage said spring, the rod, arm, and socket beinggrounded. on the shell.

In testimony whereof we aliix our signatures.
